Abstract
Idea in this work has been performed the susceptibility to intergranular corrosion of high strength aluminum alloy 2024 in aggressive corrosion environments. Intergranular corrosion is limited to the immediate area of the grain boundary and is not apparent by simple visualization and the resistance to intergranular corrosion of aluminum alloys in the Al-Cu-Mg system is related to the heating conditions applied during the solution treatment. This is can be an important source of limiting the life of the aircraft body where alloys from the 2xxx series are used, which is why they are systematically subjected to intergranular corrosion tests in dedicated laboratories.
